Welcome to the forum. Is your KP45 new? What gas are you using? When you say "stop shooting", what exactly is happening? Hammer not dropping? BBs not shooting? No gas being used? etc .....

PS. Please don't type in all "CAPS", it reads as if your shouting and it's hard to read especially for old tired eyes.
